Overview
Designed to meet the AS ISO7240.24:2018 fire/evac standard without the need for external equalisation. These horns are both compact and packed with features designed to cut down installation time. Available in grey, black and white versions.
Application
The One-Shot horn is primarily used for fire and evacuation systems where a high degree of speech articulation and program clarity is paramount. Typical applications include schools, train and bus stations, airports, car parks and plant rooms. Approved for use in Australia under the AS ISO7240.24:2018 standard (no external EQ required)
About Redback® Speaker Drivers Each horn speaker has been specifically engineered to ensure a wide frequency range and dispersion angle, plus a high sound pressure level (SPL) ensuring excellent music and speech intelligibility; which is highly desirable. Redback® horn speakers exhibit optimum frequency response and efficiency. Redback® horns are subject to strenuous factory testing reducing the risk of unit failure or performance reduction over time.
Installation Guidelines
This One-Shot horn speaker is designed to save installers time and money. Typically to terminate cabling internally on a horn speaker it involves removing three screws on the rear cover, connecting the cable and then re- installing the same screws. This process can prove quite difficult when at the top of a ladder. The One-Shot horn eliminates screw removal by utilizing a patented twist lock mechanism.
Twist lock cap makes internal termination easy! Saves time and money. Patent/registered design pending.
The installer simply twists off the rear cover, connects the cabling and twists the cover back on. The labor savings by using the One-Shot horn on a large job are significant. To further cut installation time, a patented ‘dog leg’ mounting bracket is employed which eliminates the need to separate the horn from the bracket during installation.
This model is supplied with an in-built bipolar capacitor making it compatible with EWIS control systems employing line monitoring circuitry.
Supplied with stainless steel hardware. The grey, black and white colour options provide an architecturally unobtrusive finish to virtually any installation.
